This brings up an important principle: the higher the tech, the shorter its lifespan. A cellphone from the 1980s won't function anywhere but in a Faraday-caged lab equipped with a suitable cell site, while 2G and 3G systems are fast disappearing. Only recently have landline telephone exchanges begun to drop support for pulse dialing, but otherwise, a rotary-dial desk phone from 100 years ago would still work today, and DTMF dates to 1963.

It doesn't get used much, except for the loud ringer and during extended power outages.
- imtringued 6y agoYou can get hundred year old manual lathes/mills and they still do their job. It's because the basic principle upon which they were built is still valid today. The only difference with modern machinist tools is that they are fully automated and you can just retrofit CNC parts to the old equipment.
